connector (2).

If +24 VDC is not present, go to step 4.

If +24 VDC is present, go to step 2.

Step 2. Remove two bolts (3), lamp guard (4), mount (5), and lamp (6).

Step 3. Check for +24 VDC between wire 42HR (1) and ground at socket (7).

If +24 VDC is present, replace lamp.

If +24 VDC is not present, repair wiring 42HR between socket

and auxiliary headlight connector.

Step 4. Check for +24 VDC between wire 42HR (1) and ground at auxiliary light

control switch (8).

If +24 VDC is present, repair wiring 42HR between auxiliary

headlight connector and auxiliary light control switch.

If +24 VDC is not present, go to step 5.

Step 5. Check for +24 VDC between wire 41HR (9) and ground at auxiliary light

control switch (8).

If +24 VDC is present, replace auxiliary light control switch

(page 4-1 46).

If +24 VDC is not present, go to step 6.

Step 6. Disconnect connector G (10) and check for +24 VDC between wire 41HR (9)

and ground.

If +24 VDC is present, repair wiring 41HR between

connector G and auxiliary light control switch.

If +24 VDC is not present, repair wiring 41HR between fuse
